Project Description

Gunmetal Sight Flow Indicator

This sight flow indicator is ideal for you to visually check the flow, presence, colour and condition of a liquid.

  • Minimal maintenance
  • Large viewing window to show you the contents of your pipe
  • High quality robust design
  • Pressures up to 16 bar
  • Temperatures up to 200°C
  • Short lead times
  • Designed and manufactured in the UK

STYLE ‘GP’

STRAIGHT THROUGH WITH SPOUT
Ideal for gravity feed systems, intermittent flow, liquids containing entrained air and low flow rates. This model has an integral drip lip and can be mounted in any position.

STYLE ‘GR’

TWIN ROTOR
This model has two rotors mounted close to each glass to show you if the liquid is flowing. The indicator can be mounted in any position, and the light weight rotors will operate over a wide flow range. The maximum operating temperature is 100°C.

STYLE ‘GF’

FLAP WITH SCALEPLATE
When you need to know the actual flow rate this model will give you a reading of 0 to 10 on a scale plate. Charts providing the approximate water flow rate to scale reading are available. The basic model is suitable for horizontal flow. A spring loaded flap (Style ‘GFS’) is available for vertical flow and for higher flow rates.

Options

Borosilicate glass for use with steam and condensate to a maximum working pressure of 6 Bar.
Connections available with BSPP, BSPT or NPT.
